Posterior disc protrusion is more serious and often causes painful symptoms in the lower back, sometimes accompanied by radiating pain or numbness in the lower extremities. If the cauda equina nerve is compressed, it can cause numbness in the saddle area and may affect normal function of urination and defecation as well as sexual function. Patients should take conservative treatment measures, that is, strict bed rest, not to get out of bed, even urination and defecation, and must pay attention to the warmth of the lumbar region, not to appear cold situation. In addition, you can go to the hospital intravenous drip mannitol, dexamethasone and other dehydrating anti-inflammatory drugs to relieve the edema of the nerve root caused by the protrusion, but also oral anti-inflammatory and painkilling drugs, blood circulation and nerve nourishing drugs, can play a certain role in treatment. If the effect of conservative treatment is not obvious or the symptoms have worsened, surgical treatment should be performed, usually by foraminoscopy or open surgery, to remove the herniated disc to prevent the nerve root from being irritated again, so that the symptoms can gradually improve.
